Description
Technical field
A kind of swivel reducer for hydraulic excavator installation holder structure is the utility model is related to, belongs to engineering machinery field.
Background technology
In hydraulic crawler excavator, the hydraulic gyration reductor that is fixed on the revolving dial of top, traditionally, as shown in figure 1, its
Mounting seat 3 is that an annular seat board is welded on the turntable bottom plate 1 of revolving dial, and annular seat board is provided with outer ring weld seam 2, i.e.,
Only connect in outer lap welding.When hydraulic crawler excavator works, this annular seat board stress is larger, and outer ring weld seam easily ftractures, and can cause tight
The security incident of weight.
The content of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of swivel reducer for hydraulic excavator peace
Holder structure is filled, weld strength increase is not easy to crack.
To achieve these goals, a kind of swivel reducer for hydraulic excavator mounting seat knot that the utility model uses
Structure, including turntable bottom plate, mounting seat is fixed with turntable bottom plate, in addition to the fixed part being arranged in mounting seat, the installation
Seat is connected as a single entity with fixed part；
The fixed part include the first fixed part, the second fixed part, first fixed part, the second fixed part outside with
The first outer ring weld seam is respectively arranged between turntable bottom plate；
The second outer ring weld seam, inner side and the turntable bottom plate of mounting seat are provided between the outside of the mounting seat and turntable bottom plate
Between be provided with inner ring weld seam.
As an improvement, first fixed part and the second fixed part are arranged symmetrically in the both sides of mounting seat.
As an improvement, the mounting seat is an annular seat board.
As an improvement, one end of first fixed part is square, the other end is the arc coordinated with mounting seat；
One end of second fixed part is square, and the other end is the arc coordinated with mounting seat.
As an improvement, second outer ring weld seam is arc, the second outer ring weld seam is connected as a single entity with the first outer ring weld seam.
As an improvement, the inner ring weld seam is circular weld joint.
Compared with prior art, the utility model increases by traditional annular mounting seat in the case where not increasing external diameter
Add its outer circumference, make the increase of its weld length, reach the purpose of increase weld strength, while in rotary reducer mounting seat
Also further increase weld strength using welding on inner ring, reliability is further increased.
Brief description of the drawings
Fig. 1 is existing annular hydraulic gyration speed reducer mounting base structural representation；
Fig. 2 is structural representation of the present utility model；
In figure：1st, turntable bottom plate, 2, outer ring weld seam, 3, mounting seat, the 4, first fixed part, the 5, first outer ring weld seam, 6,
Two outer ring weld seams, 7, inner ring weld seam, the 8, second fixed part.
Embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, below by drawings and Examples,
The utility model is further elaborated.However, it should be understood that specific embodiment described herein is only solving
The utility model is released, is not limited to the scope of the utility model.
As shown in Fig. 2 a kind of swivel reducer for hydraulic excavator installation holder structure, including turntable bottom plate 1, turntable bottom plate
Mounting seat 3 is fixed with 1, in addition to the fixed part being arranged in mounting seat 3, the mounting seat 3 are connected as a single entity with fixed part；
The fixed part includes the first fixed part 4, the second fixed part 8, first fixed part 4, the second fixed part 8 it is outer
The first outer ring weld seam 5 is respectively arranged between side and turntable bottom plate 1；
The second outer ring weld seam 6, the inner side of mounting seat 3 and turntable are provided between the outside of the mounting seat 3 and turntable bottom plate 1
Inner ring weld seam 7 is provided between bottom plate 1.
As the improvement of embodiment, the fixed part 8 of the first fixed part 4 and second is arranged symmetrically in the both sides of mounting seat 3,
When fixed part and turntable bottom plate 1 weld, evenly, overall structure is more firm for the both sides stress of mounting seat 3.
As the improvement of embodiment, the mounting seat 3 is an annular seat board；Further, first fixed part 4
One end is square, and the other end is the arc coordinated with mounting seat 3；One end of second fixed part 8 to be square, the other end be with
The arc that mounting seat 3 coordinates, by using the fixed part unitary design of mounting seat 3 and first and second, is not increasing mounting seat external diameter
In the case of, somewhat increase seat ring length, when it is welded on turntable bottom plate 1, outer ring fusion length greatly increases, Jin Erda
To the purpose of increase weld strength.
As the improvement of embodiment, second outer ring weld seam 6 is arc, the second outer ring weld seam 6 and the first outer ring weld seam 5
It is connected as a single entity, effectively increases the weld strength between mounting seat 3 and turntable bottom plate 1.
As the improvement of embodiment, the inner ring weld seam 7 is circular weld joint, further increases weld strength, makes reliability
Further increase.
Traditional annular mounting seat in the case where not increasing external diameter, is increased its outer circumference, made by the utility model
The increase of its weld length, reach the purpose of increase weld strength, while also using weldering on the inner ring of rotary reducer mounting seat
Connect, further increase weld strength, reliability is further increased.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent substitution or improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
